Real-time stuff is a must - something like RTAI.
Things like Linux Trace Toolkit - soone or later you have to start
using them to tune performace.
Patches to remove mandatory (for 2.2/2.0) PCI/IDE support were pretty
common too.
Patch to shrink network hashes - norm of life.
Patch to kill PCI names database.
And this is only things I was using personally (and I remember about)
in my short 4 years carrier.

CONFIG_TINY - http://lwn.net/Articles/14186/ - got something like
this merged? - so I'm the first guy in the download queue on ftp.kernel.org!

Kernel heavily tuned for servers and workstations (read - modern PCs).

At my previous position company was using kernel prepared by Karim
Yaghmour and right now we using kernels from MontaVista.
Far from vanillas.

Sure complaining.
For some reasons all "improvements" to kernel had lead to increase of
kernel size, not decrease. Strange, isn't it?
